[texts]18. Eng Microstrip Satyandra Singh Lodhi - Satyandra Singh Lodhi & P. K. Singhal
This paper propose a novel design of microstrip Yagi-Uda antenna at 2.45 GHz for ISM (industrial, scientific and medical) band application. The proposed antenna consists of pair of reflector, a driven element and three directors.                   The antenna had achieved directivity of 5.95 dBi, gain of 4.496 dB, return loss of -41.5 dB and high efficiency. It has been fabricated on the FR-4 substrate with dielectric constant of 4.4, loss tangent of 0.02 and substrate height 1...
